"rolls over" every 20 years, and the first such rollover will be during
<August of this year. The problem is expected to cause problems in some
<receivers, perhaps causing erroneous output (unlikely) or possibly "loss o
<acquisition" when the receiver decides to listen to the wrong constellation
The system does not lock if the geometry is poor or the required tests fail.
It's designed to not give error filled results. I'd bet though it will ride
through it with minimal problems as most aircraft GPS use multiple sats and
the really big ones like on Commercial also have inertial systems to check
against. None fly single system and the whiskey compas is still there
to check the tube!
